The present invention relates to a machine for working wood panels or the like.
In more detail, the invention relates to a machine for processing wood panels or the like, such as a saw or cutting machine equipped with a circular cutting blade / a circular cutting blade, and a measuring system for automatically aligning the center planes of said circular cutting blades. and cut leaves.
In the field of processing wood panels or the like, it is known to make sawing or cutting machines comprising a base, a substantially horizontal support plane for one or more overlapping plates, a circular cutting blade and a circular cutting blade, such circular blades substantially have parallel axes of rotation, and protrude in use over said carrier plane.
The circular blade has the task of the desired processing on the wooden plate, i. usually perform the opening of the same plate.
On the contrary, the circular sipe blade has the task of avoiding the lower splitting of the plate caused by the aperture by creating a groove on the lower surface of the same plate prior to such machining.
In sawing machines, the slab is usually placed at the slab level to the circular slit and circular cutting and slicing section of the slab. 02/05/2014 12:43 2/29 R447 P.005 / 033 02/05 2014 12:33 FAX +4315339250 HAFFNER & KESCHMANN 1006/033 ······················································ ··· ··· · · · · · ··· «···« «····· 2
Cut leaves moves by doing in this way a groove on the lower surface, and performs the desired cut.
On the contrary, in sawing machines, the circular cutting and cutting blades are usually connected to a carrier, the so-called blade carriage, which is movable along the base of the same machine so as to move the said circular blades towards the wooden plate. wherein the groove on the lower surface and the desired cut are performed.
The relative movement between the wooden plate and the circular cutting and sizing blades defines a so-called cutting line which represents the intersection between the median plane of said wooden plate and the median planes of said circular cutting and sizing blades.
Furthermore, the circular cutting and sizing blades each have a majority of cutting teeth.
The majority of the cutting teeth of the circular sipe blade may have a trapezoidal shape whose base faces the axis of rotation of the same circular blade, or may have an inverted trapezoidal shape whose base is externally facing the same circular blade.
In the case of a majority of trapezoidal teeth is 02/05/2014 12:43 3/29 R447 P.006 / 033 02/05 2014 12:33 FAX +4315339250 HAFFNER 8 KESCHMANN @ 007/033 ···· ···· 9 999 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 999 9999 999 3 the length of the groove is also a function the penetration depth of the circular incision blade in the wood panel, whereas in the case of a majority of teeth having an inverted trapezoidal shape, the width of the groove is not a function of the depth of penetration of the circular incision blade in the wood panel;
Therefore, usually in sawing or cutting machines, the circular cutting blade has a further degree of freedom with respect to the circular cutting blade to adjust the depth of immersion in the plate, and as a result, the length of the groove on the lower surface of the same plate.
It is known in the field of woodworking or the like that in sawing or cutting machines it is necessary to replace the circular cut and cut sheets as a function of the type of sheet to be worked or the degree of wear of the same circular sheets.
However, such an exchange step of the circular blades requires a subsequent alignment step of the middle planes of the circular blades so that the circular sipe blade is capable of working the correct groove on the lower surface of the disc by preventing them from splitting during the piercing step ,
Such an alignment step of the middle planes of the circular leaves is usually done in such a way that the circular incision sheet axially until 02/05/2014 12:44 4/29 R447 P.007 / 033 02/05 2014 12:33 FAX + 4315339250

The alignment step can also be done manually, for example by means of subsequent tests on test plates or automatically when using sensors and actuators. For the automatic alignment of the middle planes of the circular cutting and sizing blades, it is necessary to know the position of said middle planes with respect to a label associated with the sawing or cutting machine.
The location of the medial plane of a circular blade with respect to an indicia can be determined such that one knows the geometrical parameters of the majority of cutting teeth and the position, with respect to said indicia, of the two end planes which limit the axial thickness of the same circular blade ,
It follows that such end planes are parallel to each other and perpendicular to the axis of rotation of the circular blade and tangent to the majority of cutting teeth.
In the automatic alignment systems, the plies of the two end planes, which bound the axial thickness of the circular blade, and the plies of the two end planes, which are the axial thickness of the plane, are aligned.

The manual override systems have the disadvantage that they require long regulation times and the use of examination material.
The automatic alignment systems, although they have reduced control times and do not require the use of test material, have the disadvantage of being very expensive due to the use of sophisticated sensors such as laser sensors.
